Carbon Steel Blind Flanges

Blind carbon steel flanges are flat, with no bore or hub, and are typically bolted onto the flange at the end of the pipe or valve. This creates a tight seal that prevents any fluid or gas from escaping. Blind carbon steel flanges are available in a variety of sizes and pressure ratings to suit different applications.

Carbon Steel Socket Weld Flanges

Socket weld carbon steel flanges have a recessed area, known as a socket, that allows the pipe or fitting to be inserted into the flange. The socket is then welded to the pipe or fitting to create a secure and leak-proof connection. Socket weld carbon steel flanges are commonly used in high-pressure applications.

Carbon Steel Orifice Flanges

Orifice carbon steel flanges are designed with a raised face that is specifically machined to accommodate the orifice plate. The orifice plate is inserted between the two flanges and then secured in place with bolts. This creates a precise flow restriction in the pipeline, which allows for accurate measurement of the flow rate.

Quality of Carbon Steel Flange

One of the most critical factors that affect the quality of Carbon steel flanges is the manufacturing process. Carbon steel flanges are typically manufactured using forging or casting methods. Forging is generally considered to be the superior method, as it results in a more homogeneous and refined grain structure, which provides improved strength and toughness compared to cast flanges. Additionally, the quality of the raw materials used in the manufacturing process can also impact the quality of the final product. Another critical factor that affects the quality of Carbon steel flanges is compliance with industry standards and specifications. Carbon steel flanges must meet certain industry standards and specifications, such as ASME B16.5, ASME B16.47, ASTM A105, and ASTM A350, to ensure that they are of appropriate quality and suitable for their intended use. In summary, the quality of Carbon steelflanges is essential to ensure the safety and reliability of industrial systems.
